To aZZ whom it may concern.-

Be it known that I, AARON T. CLARK, of Newburg, in the county of Orange and State of New York, have invented a new and useful Improvement in Felting-Rolls for Hat-Sizing Machines, of which the following is a full, clear, and exact description.

This invention relates to felt-ing or sizing rolls of machines for sizing for or wool hats, which are of a yielding construct-ion on their acting surfaces, for the purpose of doing away with that hard or abrading action on the hatbodies placed between the felting rolls or rollers, which takes place when rigid rolls having rigid longitudinal strips on their exterior are used.

The invention consists in a felting or sizing roll of a novel yielding construction on its acting surface and throughout the main portion of its body, and which, unlike longitudinal ribs or yielding rods on its acting surface, has a continuous yielding spiral pressure-like action upon the hat-bodies, thereby making the quality of work done by it more even and more closely resembling the same work as done by hand, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a longitudinal view of a felting roll or roller embdying my invention, a portion of the cover or clothing of the roller being removed. Fig. 2 is a transverse section upon thelinexmin Fig.1; and Figs. 3 and]: are diagrams showing, respectively, an end view and partly-broken top view of three of the rollers as arranged for action.

The invention is not restricted to any particular build of hat-sizing machine or the number of felting-rollers used in it; but for the con venience of explaining the construction and action of the roller, which is the subject of the invention, three felting'rollers are shown in diagrams Figs. 3 and i, the upper one ofwhich may, as usual, be carried by a hinged orswinging frame adapted to move said roller to or from the lower ones, and all the rollers be suitably driven to act upon the hat-bodies confined between them, as well understood by those familiar with hat-sizing machines.

Each roller A-that is, any or all of them is constructed of a rigid longitudinal center body piece or core, 7), extending from one circular head 0 of the roller to the other circular head 0 thereof. Secured-as by pins or otherwise-upon this rigid coreb are a series, com prising any number, of longitudinal strips or blocks (1, of india-rubber or other-suitable elasticmaterial, arranged to extend between the circular heads 0 c radially around the core I). Outside again of these elastic longitudinal strips and upon or around them is a spiral spring, e, extending throughout the length of the roller and secured at its ends in any suitable manner upon the circular heads a c of the roller. Acovering or clothing, f, in the form ofa hose, and which may be of leather or any suitable flexible fabric or material, is then slipped and seen red to its place over the spiral spring 0. This completes the roller or acting portion or body thereof.

Said roller, when in action upon the hat bodies, operates in a soft and yielding manner upon said bodies, with all the necessary firinness, however, to produce the desired effect, the metallic springc giving a certain stiff but yielding support to the coveringf, and the elastic strips or blocks d supporting in an easy yielding manner the spring 6 throughout its length. The spiral spring 6, too, unlike mere longitudinal strips or rods, does not act at intervals upon the roll of hat-bodies in planes which are longitudinal with said roll, but opcrates in a continuous manner transversely to the roll through the flexible covering f upon said roll, after the fashion ofhand-felting,which produces a more even and better quality of work.

In grouping a series of these rollers A together, as necessary to perform the work, one or more of them should have its spiral-spring support 6 arranged to run in a reverse direc tion to the springs of the other rollers, so as to avoid the working of the hat-bodies more to one end than to the other end of the rollers. Thus in machines using three felting-rollers, which is a very common construction, the up per roller should have its spring earranged to run in a reverse direction to the springs c c of the two lower rollers, as shown in Fig. 4.

Having thus fully described myinvention, I

claim as new and desire to secure by Letters tion of the central longitudinal body-core, I), Patent the longitudinal elastic strips or blocks d, the l. TheWithin-described felting roll or roller spiral spring 6, secured at its ends upon the for hat-sizing inachines, consisting of a central heads of the roller, and the outer flexible 00v- 5 rigid body-core, yielding supports outside of ering or clothing, f, essentially as shown and 1 said core, a spiral spring encircling said yielddescribed.
